Psychotria uahukensis

Declining

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Psychotria uahukensis faces severe threats from habitat destruction due to agricultural expansion and urban development on its native Hawaiian island. Invasive plant species compete directly with this endemic coffee family shrub, altering the understory composition of its native forest habitat. The species' extremely limited range makes it particularly vulnerable to stochastic events and climate-related changes affecting montane forest ecosystems.

Threat summary

Habitat

This endemic Hawaiian shrub inhabits native montane wet forests, typically growing in the understory of ohia-dominated ecosystems at elevations between 1,000-2,000 meters. It requires the humid, shaded conditions characteristic of Hawaii's native mesic to wet forest zones.
